For any new connections to the Council's wastewater network, on any of the schemes, you will require a building consent and an application must be made to the Wastewater Asset Manager.

Visit the Request a Wastewater Connection page for more information.

If you are part of one of the Council’s five STEP schemes, or have your own on-site disposal field, care of your septic tank is crucial to its successful operation. The septic tank, pipework to the boundary and pumps are the responsibility of the property owner.

Below are a few points to assist in looking after your septic tank system.

How to Use Your Septic Tank

Provided it is properly cared for, your septic tank is a simple and effective means of effluent disposal and will give you many years of reliable service. Remember to:

Reduce Sludge Build-Up

• DO scrape all your dishes to remove fats and food particles before washing
• DO keep all possible solids out of your system
• DON'T use a waste disposal unit
• DON'T pass sanitary napkins, disposable nappies etc. into the system.

Conserve Water

• DO install water saving devices, e.g. dual flush toilets
• DO take showers instead of baths
• DON'T wash clothes until you have a full load.

Regular Maintenance

By following a simple maintenance programme you can ensure that you will continue to have an efficient and healthy disposal system for many years.

Clean the Septic Tank Regularly

This should be done about every three years to remove the build-up of solids in the tank and the date recorded for future reference. If you need advice, contact your local cleaning contractor or the Council wastewater department.

If you are connected to a Council wastewater STEP scheme, the cleaning of the septic tank is carried out by the Council every three years and is paid for as part of your annual rates.

Keep the Bacteria Working

• DO use biodegradable soaps and washing powder.
• DON’T overuse powerful bleaches and disinfectants or put chemicals or paint down the drain.

For further information on your septic tank system, look at the WaterNZ booklet: Information About Your Septic Tank.

The Council currently has six pressure sewer schemes at Tuahiwi, Fernside, Northside Country, Waikuku Beach, Stages 12 and 13 at Pegasus, Ohoka Village and Beach Grove, Kaiapoi.  For pressure sewer schemes, the pump station, pipework to the boundary and control panel are all the responsibility of the property owner.

Approved Pressure Sewer Suppliers

*Installation of any model pump station other than those specified above is subject to specific approval from the Wastewater Asset Manager.

We recommend that prospective purchasers obtain their own information from the suppliers and do their own assessment to make an informed decision before purchasing a pump station.

Septage Disposal Facility

The process for applying for and using the Rangiora septage disposal facility is outlined below.

It is important to note that the facility only accepts domestic septic tank waste and no other waste (including trade waste, grease trap waste and hydro excavation waste) is allowed to be discharged at the facility.
